All default values = 0 or marked as default=x
1)
Display depends on the general SD 54760 $SNS_MEA_FUNCTION_MASK_PIECE
2)
Correction in WO only possible for measurement without reversal
3)
For tool offset, observe the channel MD 20360 TOOL_PARAMETER_DEF_MASK
4)
Only if the "Setup additive offset" function has been set-up in the general MD 18108 $MN_MM_NUM_SUMCORR . In
5)
addition, the general MD 18080 $MN_MM_TOOL_MANAGEMENT_MASK , bit8 must be set to 1.
If WO "fine" has not been set up in MDs, correction is according to WO "coarse"
6)
Empirical averaging only possible for tool offset
7)
Value range for empirical mean value memory:
1 to 20 numbers (n) of the empirical value memory, see channel-specific SD 55623 $SCS_MEA_EMPIRIC_VALUE[n-1]
10000 to 200000 numbers (n) of the mean value memory, see channel-specific SD 55625
$SCS_MEA_AVERAGE_VALUE[n-1]
If Y axis is available on the machine

Val‐ UNITS: Machining plane G17/G18/G19
ues:
0 = Compatibility, the plane active before the cycle call remains active
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
